BMC student to address medical imaging researchers

Dr. Justin Grant, program manager of the STTARR Innovation Centre at MaRS in Toronto, invited Polley, a year I MScBMC student, to address STTARR researchers. Polley’s presentation will demonstrate how biocommunicators use image processing to create 3D models.

Abstract: Surgical trainees face the challenge of reconstructing three-dimensional (3D) mental representations of anatomical structures and relationships from two-dimensional (2D) images provided by modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). Traditionally, these complex spatial relationships have been taught using a combination of cadaveric dissections and hands-on training. However, limitations with respect to the availability of time, space, and specimens have forced some medical schools to seek alternative instructional strategies. Advances in 3D imaging techniques have made utilizing interactive, virtual models a viable option for such curricula.

This talk will provide a pipeline for creating 3D interactive anatomical models from CT scans. Specifically, I will discuss producing 3D surface renderings using the DICOM imaging software, OsiriX; retopologizing meshes in 3D-Coat; and rapidly developing interactive 3D content in Unity. Past work by Biomedical Communications students, faculty, and professionals will be showcased, including medical educational games and augmented reality applications for the iPad. Finally, current work on improving learning outcomes by integrating 3D models with natural user interfaces will be presented, and will include a demonstration of the Leap Motion Controller.
